Everything you need to start building
Luma keeps the language small and readable, so you spend your time on ideas instead of syntax.
Reads like English
Sentences such as say, set and when do what they say. Anyone on your team can read the code.
Websites and servers
Pages, themes, forms, accounts and an API in one language, with dark mode, accessibility and a strict security policy built in.
Games and apps
Sprites, movement and scores, or windows and record tables for the desktop.
Native speed
Typed programs compile to fast native code when you need the speed.
Safe by default
Text from visitors is never run as code, and the compiler refuses unsafe values.
Every example is tested
Each code sample in each lesson is compiled or run by the test suite before the site is built, so what you copy works.
Things you can build
Every track ends with a complete project like these. Open one, press Try it and change it.
